        - updated test result for rect changes

        * fast/box-sizing/percentage-height-expected.txt: A bunch of strange empty
        clip rects are now dumping as (0,0) 0x0.

        - cleanup of Int/Float-Size/Point/Rect classes

        I did this as part of a redo of QMatrix, but I decided I should
        land this part separately.

        Eliminated the concept of a null rect or point, which used to be
        indicated by negative width and height.

        Changed right and bottom to to be, e.g., 2 for a rect at (0,0) 2x2.
        The old code followed Qt's system that says right is 1 in those cases,
        which is inappropriate for floating point, and old fashioned because
        modern graphics systems use coordinates for lines between pixels, not
        the pixels themselves.

        Other API improvements to the point, size, and rect classes. For example,
        functions named with verbs now always modify the object itself.
